[0037] The working principle of an embodiment of the present invention is as follows: when the present invention is working, when there is sufficient sunlight, the photovoltaic panel rotates on the photovoltaic bracket to track the sunlight, and the heat of the photovoltaic panel is supplied to the electric heating device 19 through the power distribution device. The electric heating device 19 heats the medium in the medium storage box 18, and the heated medium enters the concrete heat storage module 16 through the medium circulation pipeline 17 for heat storage. When there is insufficient sunlight, the concrete heat storage module 16 releases heat and transmits it to the electric power generator 8 through the thermal energy power generation device 20. The loading and unloading equipment at the bottom yard 22 hoists the weight block trolley 5 to the conveyor belt of the horizontal slideway 11 at the bottom of the mountain. The electric generator 8 rotates to lower the steel cable 7. The clamp 12 slides downward along the stainless steel chute of the slope inclined slideway 10 under the action of the roller 13. The weight block trolley 5 moves toward the slope inclined slideway 10 along the conveyor belt. The clamp 12 and the weight block trolley 5 meet at the bottom of the slope inclined slideway 10.

The conveyor belt of the top of the mountain horizontal slideway 9 moves, and the hook 14 of the clamp 12 retracts. While the hook 14 retracts, the conveyor belt of the hillside inclined slideway 10 drives the gravity block trolley 5 to move to the other end of the top of the mountain horizontal slideway 9 At the end, the loading and unloading equipment of the top yard 21 unloads the gravity block trolley 5, realizing gravity energy storage; the loading and unloading equipment of the top yard 21 hoists the gravity block trolley 5 to the conveyor belt of the horizontal slideway 9 at the top of the mountain, and the gravity block trolley 5 moves to the bottom of the clamp 12 and the hook 14 extends to hook the gravity block trolley 5. Under the action of gravity, the gravity block trolley 5 slides downward along the inclined slideway 10 on the hillside, and the hook 14 also moves downward.
